Abstract

The finger follower employs two independent lost motion arms and a rod which moves longitudinally to lock both arms. The rod is transversely mounted in the follower. In order to avoid premature locking, each arm has a chamfered surface on a top wall to force the rod out of engagement with the arm during upward movement of the arms, to protect premature movement of the rod from an unlocked position to a locked position.
